4 Applications of the LI system Supplying large amounts of power over long distances for infrastructure and industry High-rise structures Modern infrastructure and industry depend on a supply of electrical energy that is safe, flexible, reliable, and efficient. The LI system is the right solution to these require ments. For example, a high degree of protection, a high short-circuit rating, and low voltage drop ensure optimum operational reliability combined with maximum personel safety and efficient operation. Typical demands Low fire load Low space requirements Flexibitlity of tap-off units The flexibility of its tap-off units and a compact design support efficient planning and installation as well as a cost-effective infrastructure. Furthermore, as part of the SIVACON 8PS and TIP portfolio, the LI system contributes to integrated and future-proof solutions. High-rise buildings need a flexible and reliable power supply in the smallest possible space. Demands vary depending on how the building is used, but safety is always the top priority, and functional endurance in case of fire is a key consideration. In case of fire, the LI system helps safeguard life and infrastructure due to low fire loads as well as fire barriers in accordance with European Standards (tested according to EN and classified according to EN ). 4

5 Data centers Infrastructure Manufacturing industries Typical demands Standby power system Redundant power supply to the loads 200 % N to avoid overloads on the neutral caused by the huge amount of electronic and single-phase loads Clean Earth requirement with separate PE conductor insulated to the busbar trunking system housing Typical demands Compact design to meet the low space requirements Standby power system Redundant power supply to the loads Fire barriers in accordance with state-of-the-art safety standards Complete, design verified solution including connection between switchboard and busbar trunking system Integrated solutions for modern energy management in accordance with European Standards Typical demands Concept flexibility Flexible tap-offs for loads Reliable supply and high availability High degree of protection Tap-off units up to 1250 A TN-S grid Data centers require maximum reliability of supply and transparency in power distribution, and generally have a very large power density. Built-in redundancy is essential for data centers so as to ensure perfect reliability. A high amount of electronic and single-phase loads must not overload the neutral conductor. The LI system interconnects the UPS system and the transformers with the main distribution board. With an N conductor of 200 %, potential demands for increasing the crosssection of the neutral conductor can also be met. Tap-off units record the power consumption and transfer the data required to the control room via a separate bus system. Critical infrastructures such as airports have diverse power system requirements. The most reliable power supply possible with the lowest fire load level is required in all areas, and space must be optimally used. The LI system supports an integrated solution for an efficient infrastructure. Tap-off units can be equipped with communication-capable measuring devices that enable modern energy management. The compact design of the system allows cost-efficient buildings. Furthermore, features such as fire barriers enable to meet European building requirements for infrastructure. Manufacturing industries such as solar and microchip require large amounts of power and therefore have their own medium-voltage transformers. Power supply must be flexible to adapt to changes in the use of manufacturing areas and the introduction of new machines with different performance demands. The high power density for electrical power supply requires large rated currents for tap-off units, which can be plugged on/off the energised 1) runs up to 1250 A. The LI system provides a safe connection between the transformer and the main distribution board. Energy can be efficiently managed with communication-capable measuring devices and tap-off units with interfaces for communication via PROFIBUS, Modbus, or PROFINET. Power supply is additionally both safe with a high degree of protection, high short-circuit rating, and low fire loads and flexible due to modular, plug-on/-off tap-off units. 1) In accordance with EN (VDE ); please always observe national regulations/standards 5

20 Hook and bolt connections Safe and reliable installation Step 1 Trunking units are assembled easily and safely using hook and bolt connections with shear-off nuts for an efficient and reliable installation. Align the trunking ends with hook and bolt. Join and connect the busbar elements. Step 2 Tighten the self-torque bolt until the outer head of the nut shears off. This indicates a correct torque level of 50 Nm. Step 3 Busbar connection via hook and bolt connection The trunking units are interconnected through a hook-and-bolt technology. For this purpose, a hook is integrated on one side of each trunking unit, and a bolt on the other side. In this way, there is only one transition for each electrical conductor, ensuring a large- surface contact for an outstanding connection quality and durable elec trical contact at the same time. The mechanical connection of the elec trical conductors is established by coupling the hook and the bolt, and subsequent tightening of the bolt with a simple standard key. When the necessary clamping pressure is reached, the outer nut head is automatically sheared off. This gives simple and instant confir mation of correct assembly. After tightening the hook and bolt connection, the clamping point is covered with a connection flange. The side protection cover can only be fitted once the outer nut head has sheared off (see figure, step 2). After fitting of the protection covers the hook and bolt connection fulfils the high degree of protection IP66. Install side covers followed by top and bottom covers. Then, fasten bolts. Step 4 The final hook and bolt connection fulfils the degree of protection IP66. Your benefit Safe trunking unit connection with IP66 High connection quality with low contact resistance Higher rigidity of the system thanks to hook and bolt connection 20 Safe and reliable hook and bolt connections
